SAN discovery overview

Discovery is the process by which the Management application contacts the devices in your SAN.
When you configure discovery, the application discovers devices connected to the SAN. The
application illustrates each device and its connections on the Connectivity Map (topology).
When you discover a fabric, the Management application checks to confirm that the seed switch is
running a supported Fabric OS version in the fabric, and if it is not, the Management application
prompts you to select a new seed switch.
NOTE
Discovery of a Secure Fabric OS fabric in strict mode is not supported.
For a Fabric OS fabric, the seed switch must be the primary Fabric Configuration Server (FCS). If
you use a non-primary FCS to discover the fabric, the Management application displays an error
and will not allow the discovery to proceed. If the Management application has already discovered
the fabric, but afterward you create the FCS policy and the seed switch is not a primary FCS, an
event is generated during the next poll.
The Management application cannot discover a fabric that is in the process of actively configuring
to form a fabric. Wait until the fabric is formed and stable, then re-attempt the fabric discovery.
After fabric discovery successfully completes, all clients are updated to display the newly
discovered fabric.
During fabric discovery, you can define an IPv4 address or IPv6 address for the device; however,
the Management application uses the preferred IP format to connect with the device. To configure
the preferred IP format, refer to
NOTE
Professional edition can discover only 1 fabric.
